--- Comment #7 from Ian Lance Taylor <ian at airs dot com> ---
That's really a question for the glibc maintainers. It's entirely a glibc
issue.
My understanding is that it's not actually libc.so that needs to be found.
Glibc implements /etc/nsswitch.conf by loading a shared library for each entry
listed there ("db", "files", etc.). That is a very flexible mechanism that
allows nsswitch.conf to be extended on a system-specific basis. However, it
only works if those shared libraries are available. It is those libraries (and
libdl.so) that must be found at runtime. If the libraries can not be found,
/etc/nsswitch.conf can not be implemented, and name lookups of various sorts
fail by returning "not found."
